Shen Zhixia, the adopted daughter of the General's Mansion, was used as a substitute for marriage because of her "silliness" and was married into the home of Gu Zhaoting, the general of the country. Everyone regards her as a useless burden, but they don't know that she appears to be stupid due to being framed when she was young, but in fact she has a clear mind and has inherited her mother's top tea-making skills. She first used "silliness" as a shield to resolve the concubine's difficulties and the mother-in-law's temptation, and then used her tea-making skills to conquer the general's palace, and even helped Gu Zhaoting solve the tea supply crisis in the army. As the plot progresses, she reveals that she is the daughter of a tea-making master from the former dynasty (orphan of a fallen country). Her mother was hunted down for protecting the royal treasure, and she was adopted by the general's palace. From Gu Zhaoting's initial indifference, he was attracted by her tenacity and wisdom. Together, they faced the royal conspiracy and the pursuit of the remnants of the former dynasty, and finally protected each other and their country, realizing the "foolish girl's counterattack" and "two-way redemption."
